Be it lknownthat we, iJenn PARTMANN, asubject of the' kKing ofHungary, and aresij-y dent of they cityi of'Ne'ivYork, borough* of? Manhattan; county'of .Jllew'v York, and State oi-N'enfYorln andSMUnL BLALDA, .a subiect of the King of Hungary,and a resident ofthe'city'of Neiv`-Yorlr, borough' of Brook# lyn,.`county of Kings,vand Stateof/New" after the needles are pushed `through plaitsl in the mantle made by plaiting ,membersy so Yorlghave invented a new' anldlmproved.

which the lii'ollowing is a full,` clear',` and` exactdescription.

Our invention has for its object'toprovide a machine for stitching gas-mantles which, has hooks 4which are moved into needlev eyes that ak thread may be disposed inthe hooks to be drawn through the needle eyes when. the hooks are withdrawn therefrom priorr to.

the withdrawal ofthe needles .from the' mantle plaits, whichstitches themantle; a

' By referring to the drawings itwill be seen that on a frame'member 10 there kare mounted plaiting members 11,7`the said plait, innl members-being spaced apart at each side ofthe top of the iframe member 10. Extending above the plaiting members 11 at the central line of the frame member 10 thereis a guide 12 which assists in the disposal. of

vThe frame member 10 has flanges 15 which troduction Vof needles 41 whichl are rest,"on^p1ortions'16k of a frame member 17 the said portions 16' being's'paced apart, andwith the frame -member Y 10 disposed f there`l between', a screw' 18fbeingf employed to hold the 'frame member?A 10 Lin position relatively tothe portions 1610i the iframe' member Disposed;` between l the "portions"r 16 of' the` frame `m`em`bery 17 andpivoted; thereto'at 19,

there are'4- levers 20" which" have upwardly,-

ext'en'dingj arms f21' 'on which' plaiting members 22 'a're'imountedgthe said 'plaitingvmem bers 22"on'each of the lever arms" 21Ibeing` Specification of'Letters .'Patent. Patented dual'. 19, 1918." y

drawingsi yAs will be seen by referringto throughthe inner sides of -the said plaiting members. The lower arms 244 of the levers 20 are normally disposed adj acen'tl eachy other, the levers beingheld in this positionv by". means of'springs 25 whichv connect the arms`421 of thelevers 20 Ywith rods 26 whichy are supported on arms 27 secured to the por'-V tions16 of the frame member 17. l

A bifurcatedarm 29 of an operatinglevery 30'is pivotediat 28,r` this bifurcated arm`29" being provided withslots 31in Vwhich a pin" 32 is'disposed. The pin 32'is secured to anV armf'of a'V slide34, the" arm 33 havingan`V orice in which a plunger 36 is secured,`

the plunger BG'eXtending in a bearing'in a frame,member3S and-"in a'bearing-y 39" mounted on one of the portions '16 4of the frame member 17. The end 400i: this plunposition indicated in 'FigLG of the-drawings,V Y

the gas mantle being plaited. and held by the plaitingf members -11 and22 for the in-y v mounted at 42 onthe slide 34. The first action of the Voperatingy lever 30 serves to operate the levers 2O,l as stated, in,- asmuch as the plunger end 40operates the levers, the needles 41 being subsequently introduced through the openings 28y in the plaitingmembers 22, at lthe inner side of the plaiting members 11, and as the mantle Lis disposed in` plaited formlbetween the said plaiting members, `the needles are inserted through the mantle as'illustrated in'Fig. 6 of the drawings. Y

The slide 34 travels on a plurality of rods 43, preferably three in number, and on these rods L43 there is slidably disposed a guide 44 having openings 45 in which the needles 41 are disposed. y

When the needles 4l have been introduced through the mantle, as has been stated, the needles are threaded, this being accomplished by the movement of hooks 46 through the needle eyes 47, after which a thread 48 is disposed down between one of the hooks and the needle adjacent thereto, and then up between the other hook and the other needle. When ythe hooks 46 are then removed from the needle eyes and the needles 44 withdrawn, the mantle is stitchedin a manner which will be readily understood.

The hooks 46 are adjustably mounted on levers 49 the hooks 46 being held on the levers 49 by clamps 50 which are secured to the levers 49 by screws 5l. By Vthis means the hooks 46 may be adjusted as necessary, so that they will move freely through the eyes 47 when the machine is operated. The levers 49 are pivotedat 52 to a guideway 53, the lower Varms 54 of the levers 49 having slots in which a pin 55 is disposed, the pin extending from a guide 56 which moves in the guidewayl53. A cross-piece 57 is disposed at the Youter side of the guide 56, and is secured to the sides of the guideway 53.

VThev guide 56 is held yieldingly downwardly by a spring 5 8 which connects the guide 56 with the cross-piece 57. Mounted on the guide 56 below the cross-piece 57 there is a ring 59, and extending upwardly from the bottom of the ring 59 there is a boss 60, this boss`60 tting in a guideway 6l at the bottom of the plunger36 when the plunger moves forwardly. It will, therefore, be seen that with the plungers forward movement it willnot move theboss 60 or the ring 59 until the plunger 36 advances to a point where the boss 60 will be engaged by the shoulder 62 on the plunger. The boss 60 is .beveled at its inner side, as illustrated in Fig. 3 of the drawings, so that the shoulder.

62 will serve to press the boss 60 down and with it the ring 59, thereby moving the guide 56 down to operate the levers 49 and move the hooks 46 inwardly and through the eyes 47 of the needles 4l. lith this downward movement et' the guide 57 the lower portion 63 of the guide 56 will move down into a recess 64 at the top oi the plunger 36 and against a shoulder 65 at the rear of the said recess to check the forwardmovement of the plunger 36. As the lower end 63 of the guide 56 will rest against the plunger 36 in the recess 64, thedownward movement ot the .guide 56 will also be checked. It will be observed that the recess 64 is disposed above the shoulder 62 on the plunger 36.

Having thus described our invention, we
